Tong, Yanfeng, Li, Fengyuan, Song, Yang, Chen, Haifeng & Li, Shuqiang, 2019, Thirty-two new species of the genus Speocera Berland, 1914 (Araneae: Ochyroceratidae) from China, Madagascar and Southeast Asia, Zoological Systematics 44 (1), pp. 1-75 : 56

Speocera trusmadi Li & Li sp. nov. ( Figs 45–46 , 57D )

Material examined. Holotype ♂ ( IZCAS), Malaysia, Borneo, State of Sabah, Mount Trus Madi , Jungle Girl Camp (5º26.634′N, 116º27.079′E), elev. 1234 m, 1.V.2016, leg. Z. Chen. Paratype 1♀ ( IZCAS), same data as holotype .

Etymology. The specific name is derived from the type locality; noun.

Diagnosis. The new species is similar to S. capra Deeleman-Reinhold, 1995 , but males can be distinguished by the presence of a cluster of long setae on the lateral surface of the chelicerae ( Fig. 57D ) and the more flattened palpal bulb ( Figs 45A–B ), and the females by the oval spermathecae ( Fig. 46A ). S. capra males have the chelicerae with a lateral horn, the palpal bulb nearly round, and the females have small oval spermathecae (Deeleman-Reinhold, 1995: figs 273–279).

Description. Male. Total length 1.05; carapace length 0.50; carapace width 0.44; abdomen length 0.53; abdomen width 0.36. Prosoma: carapace pyriform, narrowing gradually anteriorly; shiny, light yellow, suffused with purplish pattern ( Fig. 46C ); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, as long as wide. Endites light yellow suffused with purplish tinge; with serrula; labium light yellow suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow, laterally excavated, with a cluster of long setae; promargin with a series of six teeth reaching the lamina; retromargin with two small denticles ( Fig. 57D ). Eyes: six contiguous eyes surrounded by black pigmentation; PME, ALE and PLE nearly subequal ( Fig. 46C ). Opisthosoma oval; purplish. Legs light yellow; leg lengths I 2.18 (0.61, 0.16, 0.63, 0.48, 0.31); II 1.99 (0.56, 0.16, 0.54, 0.43, 0.30); III, IV missing. Genitalia ( Fig. 45 ). Palpal femur long; palpal tibia about 1.2 times as long as cymbium, palpal tibia and cymbium incrassate. Cymbium conical, with large prolateral extension basally. Bulb spherical, wider than high, with a small tuberculate apophysis. Embolus a wide triangle, dark and basally without distinct associated sclerites; sperm duct initially wide, abruptly narrowing distally ( Fig. 45D ).

Female. Total length 1.18; carapace length 0.50; carapace width 0.43; abdomen length 0.61; abdomen width 0.48. Similar to male in color and general features ( Figs 46D–E ) but larger. Chelicerae unmodified. Leg lengths I 2.10 (0.59, 0.16, 0.60, 0.45, 0.30); II, III missing; IV 1.73 (0.47, 0.15, 0.43, 0.40, 0.28). Genitalia. Internal genitalia with afferent spermathecae very short, not extending past the sides of the abdomen ( Fig. 46B ); spermathecae oval ( Fig. 46A ).

Distribution. Known only from the type locality.
